Scope

GB/T 45862-2025 is the English-translated version of 锅炉碳排放测试与计算方法.

GB/T 45862-2025 is the Chinese national standard covering measuring what a boiler emits rather than estimating it from the fuel invoice — the test boundary and the emission sources of the boiler system, the test requirements, the measurement items, instruments and methods, the calculation of direct and indirect emissions and of the emission per unit of heat output, and the test report, for fossil-fired, mixed-fuel and electrically heated boilers but not waste incineration or waste heat boilers. First edition, with the online monitoring guideline GB/T 45869-2025. In force from 1 February 2026. Issued on 1 August 2025, it has been in force since 1 February 2026.
